Having these named differently than the test itself mostly creates unecessary confusion and makes writing logic against the tests harder so let's rename the testsuite-xx units and scripts to just use the test name itself.

# Notes on coverage: when collecting coverage we need the $BUILD_DIR present
|
|
# and writable in the container as well. To do this in the least intrusive way,
|
|
# two things are going on in the background (only when built with -Db_coverage=true):
|
|
# 1) the systemd-nspawn@.service is copied to /etc/systemd/system/ with
|
|
# --bind=$BUILD_DIR appended to the ExecStart= line
|
|
# 2) each create_dummy_container() call also creates an .nspawn file in /run/systemd/nspawn/
|
|
# with the last fragment from the path used as a name
|
|
#
|
|
# The first change is quite self-contained and applies only to containers run
|
|
# with machinectl. The second one might cause some unexpected side-effects, namely:
|
|
# - nspawn config (setting) files don't support dropins, so tests that test
|
|
# the config files might need some tweaking (as seen below with
|
|
# the $COVERAGE_BUILD_DIR shenanigans) since they overwrite the .nspawn file
|
|
# - also a note - if /etc/systemd/nspawn/cont-name.nspawn exists, it takes
|
|
# precedence and /run/systemd/nspawn/cont-name.nspawn won't be read even
|
|
# if it exists
|
|
# - also a note 2 - --bind= overrides any Bind= from a config file
|
|
# - in some cases we don't create a test container using create_dummy_container(),
|
|
# so in that case an explicit call to coverage_create_nspawn_dropin() is needed
|
|
#
|
|
# However, even after jumping through all these hooks, there still might (and is)
|
|
# some "incorrectly" missing coverage, especially in the window between spawning
|
|
# the inner child process and bind-mounting the coverage $BUILD_DIR
